Indigofera sphaerocarpa, commonly known as Sonoran Indigo, is a deciduous shrub native to desert scrub and arid grasslands in the Southwestern United States and Northwestern Mexico. It typically grows to a height and width of 2-3 feet (0.6-0.9 meters), with a rounded form. The plant is notable for its pinnate leaves and spherical clusters of bright yellow flowers that bloom in the spring, adding a splash of color to the landscape. The flowers are not particularly showy but do provide a subtle beauty. After flowering, it may produce small, inconspicuous legumes.

Sonoran Indigo is valued for its drought tolerance and ability to thrive in hot, dry conditions, making it an excellent choice for xeriscaping and low-water gardens. It is often used in native plant gardens, as a border shrub, or for naturalistic landscaping. This shrub prefers full sun exposure and requires well-drained soils. It is relatively low-maintenance, needing only occasional pruning to maintain its shape and promote denser foliage. While it is generally pest-free, overwatering can lead to root rot, and it may be susceptible to infestations of spider mites in particularly dry conditions.CC BY-SA 4.0
